TRACKSANDER.

SPECIFICATION forming part of Letters :Patent No. 708,473, datedSeptember 2, 1902.

Application filed April 22,1902. Serial No. 104,201. (No modela To allwhom it may con/cern:

Be it known that I, WILLIAM C. GARDNER, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented new and useful Improvements in Track-Sanders, of which thefollowing is a specification.

This invention relates to track-Sanders; and the primary object thereofis to produce a delivering device adapted to be secured to an engine ata convenient point to receive sand from the sand-box and from which thesand is discharged upon the tracks bymeans of compressed air hanst.

Another object of the invention is to produce a sand-deliverer in whichthe sand is kept perfectly dry, whereby all liability of the samebecoming caked and rendering the device inoperative is obviated.

The invention consists in the construction, combination, and arrangementof parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a central lon,- gitudinal sectional view ofa delivering device constructed in accordance with my invention. Fig. 2is a central transverse sectional view thereof. Fig. 3 is a centralhorizontal sectional View of the same.

1 designatesa rectangular chamber adapted to be secured upon the engineat a convenient point to receive sand from the sand-box and to dischargethe sand upon the tracks. The chamber is provided with a threaded inlet2 and two threaded outlets 3. The inlet 2 `receives the threaded end ofa pipe 4, suitably connected to the sand-box of an engine to convey sandtherefrom to the chamber. The outlets 3 receive the threaded ends ofpipes 5, having their opposite free ends arranged adjacent the tracks todeposit sand thereon. The chamber is provided with a removable plug 6 inthe bottom thereof to permit the sand to be removed therefrom when foundadvantageous to clean or repair the chamber. A partition 7 is arrangedwithin the casing and provided with passages 8, having oppositedischarge-openings 9, carrying jet-nozzles l0. Communicating with thebeginning of the passages are threaded inlet-openings 11, adapted toreceive the threaded ends of air-pipes 12, suitably connected with thefromv the air reservoir or ex-` compressed-air reservoir or the exhaustto convey air therefrom to the passages 8, discharging sand upon thetracks in` a manner asis obvious. The pipes 12 are provided with valvesto be controlled by the engineer to permit the regulation of the amountof sand to be discharged upon the tracks.

It will be perceived that when sand is let into the chamberl and whenthe compressed air is permitted to pass through the passages 8 the sandis forced through the pipes 5 in jets to be deposited upon the trackthrough the medium of jet-nozzles 10, which reduces the stream of air toa jet.

The chamber 1 has the sides and edges thereof provided withcommunicating steampockets 13, and one side thereof is provided with athreaded inlet 14, adapted to receive the threaded end of a pipe 15,having its opposite end suitably connected to the steamchest or theexhaust to supply pockets with steam. The pipe 15 has arrangedintermediate its ends to be within easy reach of the engineer to enablehim to control the supply of steamin the pockets 13 a valve. Asteamexhaust 16 is arranged on the chamber upon the opposite side tothat of the inlet 14 and at an extreme point near the lower end thereoftoinsure against all liability of condensation remaining in the pockets.The exhaust is of a diameter much smaller than the inlet, whereby theexhaust of steam is much slower than the feeding thereof, whereby thepockets are at all times sufficiently su pplied with steam. The exhaustof the steam, although it be slower than the feeding thereof, will notpermit the condensation of the steam in the pockets to any great extent.

It will be perceived that by surrounding the chamber with steam -pocketsthe sand contained therein will be kept dry at all times, therebyobviating any liability of the sand becoming clogged, and consequentlyrendering the device inoperative.

The operation of the device will be clearly understood from the abovedescription, taken in connection with the accompanying drawings, andtherefore a further description is deemed unnecessary.

It will be obvious from the description and drawings that I provide adevice which will effectually prevent the sand from becoming IOO cloggedfrom moisture and by means of which sand may be deposited upon thetracks and which is cheap, durable, and efficient.

Having thus fullydescribed the invention, what is claimed `as new isl. Atrack-sander, comprising a sand-receiving chamber surrounded by asteampocket, and a sand-discharging device arranged within the chamber.

2. A track-sander, comprising a sand-receiving chamber surrounded by asteampocket, a sand-discharging device arranged within the chamber, andjet-nozzles carried by the discharge device.

3. A track-sander, comprising a sand-receiving chamber surrounded by asteampocket, said chamber being provided with outlets, asand-discharging device arranged Within the chamber, and provided withdischarge-openings alined with the outlets, and j et-nozzles carried bythe discharge-openin gs.

4. A track-sander, comprising a chamber surrounded by a steam-pocket,means for feeding sand thereto, a partition arranged Within the chamberand provided with passages having opposite discharge-openings,jet-nozzles arranged in the discharge-openings, means for feeding steamto the passages to discharge the sand, means for supplying steam to thepockets, and an exhaust adapted to con trol the supply of steam in thepockets.

5. A track-sander, comprising a sand-receiving chamber surrounded by asteampocket, and a sand-discharging device arranged within the chamber,and formed integral therewith.

6. A track-sander, comprising a sand-receiving chamber surrounded by asteampocket, and provided with outlets, a partition within the chamberand formed integral therewith, said partition being provided withpassages having oppositely-located inlet and discharge openings.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM C. GARDNER.
